Never disassemble an eyepiece unless you know exactly how to put it back together. Only the outer glass lens ever needs cleaning.

Without knowing exactly what link of eyepiece you have (they are all different designs) it's impossible to tell you which way the internal lenses go.

Your best bet may be to simply purchase another eyepiece.

This is a small 60mm refractor telescope. The main lens probably screws on the from of the telescope.

You will also have a small finder scope that mounts on top of the main tube.

Several eyepieces

and a diagonal.

You may also have a 2x barlow.

Put the diagonal into the back of the telescope, then put the eyepiece into the diagonal. That's it.

Now practice focusing on a distant object during the day time. Read my tips on my profile page, and read this:

Bushnell Spotting Scope has extra power for extra range; its BaK-4 Porro-prism design delivers magnificent clarity in a traditional design. The multicoated optics ensure maximum light transmission for the brightest and take the images more colorful and clear. If you are searching Bushnell Scope that can be used for different activities, you should consider Bushnell Trophy Xtreme Spotting Scope Review.
The highly refractive BAK4 Porro prisms diminish spherical deviations for increased edge-to-edge sharpness and help progress depth of view. This combination of optics and coatings creates a spotting scope that produces clear, bright, highly contrasted images with the exact color transmission.
The rubber-armor structure stands up to demanding use. This scope is 100% waterproof and fog proof for wet hunting conditions. It also Comprises compact tripod with window mount, compact soft case, and waterproof hard case.

  • Close Focus Distance:25 feet
  • Length:13 inches
  • Weight:31.4 ounces
  • Field of View:125-60 feet/1000 yards
  • Eye Relief/Exit Pupil:16 mm/ 3.1-1 mm
  • Optics Coatings:Fully Multi-Coated

  • Focus System:Focus Knob/Single Focus
Feature Analysis
  • Porro Prism Lens
    Though many optics producers keep on trying to transform roof prism lens, Porro prism lenses are more affordable and light-efficient. These Porro prism lenses can display images with better contrast than roof prism variations. This is how Bushnell Spotting Scope is more reliable and affordable for its high-quality performance.
  • 20-60×65 Zoom Magnification
    The wide range of magnification allows user flexibility for long-range view finding. You can observe details with 65x zoom for long range objects. But, you can still enjoy an increased field of view with 20x zoom. This is used when separating the areas for closer zoom viewing later on.
  • 65x Lens Light-Gathering Capability
    This advanced magnification lenses can light gather at long distances. The Bushnell Trophy 20-60x 65mm Waterproof Spotting Scope resolves this issue by designing 65x zoom lens in a way that brings 17% more light than most high-zoom lenses.
    If you fully read Bushnell Trophy Xtreme Spotting Scope Review, it will support you how to setting zoom for longer distances images.
  • Waterproof Construction
    When you go out in nature, this waterproof construction anticipates you about rain or even snow. It is pretty obvious that any liquid that leaks into your scope will detract from the overall image. But many people do not consider the effects of concentration on the inside of the lens.
    This spotting scope is actually water and fog proof not only for outside moisture but also prevents lens fogging from risky temperatures.
  • Fully Multi-Coated Optics
    The multi-coated lenses prevent any reflections in the glass that can delay your view. The sunlight at certain angles can cause reflections from water or wet surfaces that prevent the clear view of the images. That is why; Bushnell uses multi-coated lenses to remove any kind of reflection.
  • Well-designed Equipment
    The tripod often needs to hide from animals, and the scope cases also need to protect their insides from both jostling and the outside elements. The Bushnell Trophy XLT comes with both a hard-side case and a soft side case. The hard side case protects you from outside damage and a soft-side case protect you from a bumpy road when you are riding.

What is a digiscoping?


Digiscoping is the practice of shooting digital photos through a Spotting Scope.The telescope magnifies the subject image for the camera, just as it magnifies the subject image during visual use.
The magnification is usually in the range of 20x to 60x for spotting scopes typically used by birders.

Yes you bent the shaft on the knob or the gears inside the focuser. Order another complete focuser from Leica.

How do I properly arrange the objective lenses in the Meade 285?


The OBJECTIVE lens is the one in the front of the scope-- you DID NOT take it apart did you?

You only needed to clean `the outside of the glass elements. Read my tips on my profile page about why you never disassemble these and or eyepieces completely.

Image upside down


Hi, this is a common "problem" for astronomical telescopes. Same with my Meade 3" refractor and spotter. It is actually a design 'feature' not broken.

The issue is that most astronomical telescopes naturally show images upside down, or some combination of upside down and left-right.
(Astronomers usually don't care, because space has no up or down.)
It is just the way optics work when lenses or mirrors bounce and bend light. (And since the professional astronomer wants the most light and most direct image, they usually don't want extra devices just to make it right-side up.)

Reason that binoculars don't do that , is they employ special internal prisms to get the image back right-side up.

Easiest solution for astronomical telescope is to buy what is called a "star-diagonal" or "image-erector prism". These will usually make the image look normal for us earth-based folks.

I do not know what exact type your Meade 227 telescope is, but the spotter scope is most likely a simple refractor. So it MAY be possible to install a star diagonal onto it. Or might not. Depends on the exact spotter scope design.
Another option may be able to buy a replacement spotter scope that is designed for correcting image orientation.
